Apparatus and methods for tubular makeup interlock
View Patent ↗Apparatus and methods may be used to prevent an operator from inadvertently dropping a string into a wellbore during assembling and disassembling of tubulars. Additionally, the apparatus and methods may be used for running in casing, wellbore components, or a drill string.
1. A system for connecting casing sections to a casing string, comprising:
a top drive system comprising a radially movable gripping member for gripping a casing section;
a processing unit for receiving a signal from the top drive system indicative of operational data of a casing connection between the casing section and the casing string, wherein the processing unit is operable to control actuation of the top drive system; and
a user interface for conveying the operational data of the casing connection to an operator.
2. The system of claim 1 , wherein the radially movable gripping member comprises a slip for engaging an inner surface or an outer surface of the casing section.
3. The system of claim 1 , wherein the processing unit is programmable and comprises data storage and memory, and wherein the user interface comprises a display unit.
4. The system of claim 1 , wherein the processing unit is operable to compare the operational data to at least one pre-programmed value.
5. The system of claim 1 , wherein the operational data comprises at least one of a torque value, a rotation value, a stroke value, an axial load value, and a pressure value.
6. The system of claim 1 , wherein the operational data comprises a torque value applied by the top drive system to the casing connection, and wherein the top drive system further comprises a torque sub for measuring the torque value.
7. The system of claim 1 , wherein the operational data comprises a rotation value applied by the top drive system to the casing connection, and wherein the top drive system further comprises a rotation counter for measuring the rotation value.
8. The system of claim 1 , wherein the operational data comprises a stroke value of the top drive system during make-up of the casing connection, and wherein the top drive system further comprises a compensator to axially stroke the radially movable gripping member.
9. The system of claim 1 , wherein the operational data comprises an axial load value supported by the top drive system during make-up of the casing connection, and wherein the top drive system further comprises a sensor for measuring the axial load value.
10. The system of claim 1 , wherein the operational data comprises a pressure value of the top drive system during make-up of the casing connection, and wherein the top drive system further comprises a sensor for measuring the pressure value.
11. A system for connecting casing sections, comprising:
a top drive system comprising a radially movable gripping member for gripping a casing section;
a processing unit for receiving a signal from the top drive system indicative of operational data of the top drive system, wherein the processing unit is operable to control actuation of the top drive system; and
a user interface for conveying the operational data to an operator.
12. The system of claim 11 , wherein the radially movable gripping member comprises a slip for engaging an inner surface or an outer surface of the casing section.
13. The system of claim 11 , wherein the processing unit is programmable and comprises data storage and memory, and wherein the user interface comprises a display unit.
14. The system of claim 11 , wherein the processing unit is operable to compare the operational data to at least one pre-programmed value.
15. The system of claim 11 , wherein the operational data comprises at least one of a torque value, a rotation value, a stroke value, an axial load value, and a pressure value.
16. The system of claim 11 , wherein the top drive system further comprises a torque sub for measuring the operational data.
17. The system of claim 11 , wherein the top drive system further comprises a rotation counter for measuring the operational data.
18. The system of claim 11 , wherein the operational data comprises a stroke value of the top drive system, and wherein the top drive system further comprises a compensator to axially stroke the top drive system, and a sensor to measure the stroke value.
19. The system of claim 11 , wherein the operational data comprises an axial load value supported by the top drive system, and wherein the top drive system further comprises a sensor for measuring the axial load value.
20. The system of claim 11 , wherein the operational data comprises a pressure value of the top drive system, and wherein the top drive system further comprises a sensor for measuring the pressure value.
21. The system of claim 11 , wherein the top drive system further comprises one or more sensors coupled to the top drive system for measuring the operational data.
22. The system of claim 11 , wherein the operational data comprises a position of the gripping member.
